1. Question 241 · 279 in bank

   An org has a requirement that an Account must always have one and only one Contact listed as Primary. So selecting one Contact will de-select any others. The client wants a checkbox on the Contact called 'Is Primary' to control this feature. The client also wants to ensure that the last name of every Contact is stored entirely in uppercase characters. What is the optimal way to implement these requirements?

   • AWrite an after update trigger on Contact for the Is Primary logic and a separate before update trigger on Contact for the last name logic.
   • BWrite a Validation Rule on the Contact for the Is Primary logic and a before update trigger on Contact for the last name logic.
   • CWrite an after update trigger on Account for the Is Primary logic and a before update trigger on Contact for the last name logic.
   • DWrite a single trigger on Contact for both after update and before update and callout to helper classes to handle each set of logic.

   Answer: D

   Explanation

   For me it is D. C does not make sense for me, because how you will control is Primary when you will be adding a new contact if the trigger is in Account? Also, for me, the best solution is a trigger in Contact for Is Primary and a validation rule for the LastName

6. Question 246 · 279 in bank

   A developer has been asked to create code that will meet the following requirements: Receives input of: Map<Id, Project_c), List<Account> Performs a potentially long-running callout to an outside web service Provides a way to confirm that the process executed successfully Which asynchronous feature should be used?

   • A@future (callout=true)
   • BDatabase.AllowCallouts interface
   • CSchedulable interface
   • DQueueable interface

   Show answer

   Answer: D

   Explanation

   So ignoring the part that B is spelled wrong, D is needed for several reasons, most already mentioned. There is a second part to this though that allows for the queueable process to be reviewed, and this is generally handled with a transaction finalizer.
